Surreal giant mushroom city under auroras and rainbow waterfalls

A surrealist painting of incredible detail, ultra-HDR, and striking visual effects; 16:9 format. Giant iridescent mushroom, radiant multicolored cityscape inside, vibrant jewel-toned trees spiraling through intricate architecture, cascading rainbow waterfalls, luminous mist, under starry night sky with swirling auroras, in hyper-detailed, hyper-maximalist style, reminiscent of Simon Stalenhag, Syd Mead, and Ash Thorp, with prismatic volumetric lighting, vivid dynamic shadows, and deep complementary colors. Volumetric lighting, ultra-sharp focus, crystal clarity, extreme contrast, visual effects, ultra-high-quality CGI rendering (16K), brilliant and vibrant colors, magical fantasy aesthetic, hyper-detailed, concept art, and dark fantasy elements. Precise focus, fantastic realism. Professional, realistic, and natural photography; natural lighting, sharp focus.
